Introduction:

Graphical representations of data are used as visual aids to convey information in a clear and concise manner. From line graphs to pie charts and bar charts, these tools allow us to easily analyze complex data and to draw conclusions from it. In this discussion, we will examine the purpose of a specific graph from a newspaper website and the importance of using graphical representations for effective communication of information.

Description:

In the e-Activity for week 2, we were asked to select a line graph, pie chart, or bar chart from a newspaper website and discuss its relevance. The purpose of using graphs in newspapers is to provide readers with a quick and easy way to understand complex data. By visually representing information, it enables readers to comprehend the information presented quickly and efficiently.

The editor chose the graph to convey its message without using a lengthy paragraph to explain the data. For example, a pie chart can represent the proportion of different countries’ population size in a specific region, making it easy to comprehend the data. Similarly, a line graph can show correlation and change in the value of a particular stock or commodity over time.

In addition to newspapers, graphical representations of data have become increasingly popular in various other fields, including business, marketing, and science. In the following session, internet resources are suggested for supplementary study, including Kahn Academy videos that explain various types of graphical representations of data, such as histograms, stem-and-leaf plots, and pie charts. Understanding these can help learners appreciate the role of graphical depictions of data in academia and other spheres.

Objectives:
– To understand the importance of graphical representations of data
– To be able to identify which type of graph is appropriate for certain types of data
– To be able to interpret and analyze data presented in graphical form

Learning Outcomes:
– By the end of the lesson, students will be able to explain why graphical representations of data are preferred over table formats
– Students will be able to correctly identify the type of graph used for different types of data, such as line graphs, pie charts, and bar charts
– Students will be able to accurately interpret and draw conclusions from data presented in graphical form

Discussions on Graphical Representations of Data:
The graph chosen by the editor visually represents a fluctuation of stock market prices. The fluctuations occurred over a period of time, represented on the graph’s x-axis, while the stock values are represented on the y-axis. The editor opted for a line graph as it is ideal for representing data that changes over time. The fluctuations in the data are shown clearly on the line graph, making it easier for readers to interpret and understand the data. Unlike tables, line graphs have the added advantage of enabling one to predict future trends and observe patterns, which is an important aspect when dealing with stock market values.

Discussion on E-Activity:
For this e-activity, I have selected a pie chart from the Washington Post. The chart represents the results of a survey of adults and their use of social media. Pie charts are ideal for showing proportional data, and in this case, the data represents various social media platforms used by the surveyed individuals. The chart makes it easy to interpret the data, as specific categories, such as Facebook and Twitter, are color-coded and labeled. The editor chose the pie chart as it visually presents each social media platform’s usage, making it easier to highlight the differences in data values.

Discussion on Internet Resources:
Khan Academy is an excellent supplementary resource for students to explore. The videos titled “Histograms,” “Reading Pie Charts,” and “Reading Stem-and-Leaf Plots” from the resource library are particularly useful for this week’s lessons. Histograms are bar graphs that display continuous data, making them ideal for representing data sets in the form of ranges. Pie charts, on the other hand, provide data in the form of percentages and are used to illustrate how parts relate to the whole. Stem-and-leaf plots, meanwhile, are used to represent large sets of data. These tools are valuable to learn in the context of graphical representations of data and will enable students to choose the best option for their data and make accurate conclusions.

Solution 1: Graphical Representations of Data

Line graph displaying the number of COVID-19 cases over time

The line graph visually represents the data of the number of COVID-19 cases reported over time in a particular region. The graph shows the trend of the cases increasing or decreasing over time, which helps in understanding the severity of the situation. The editor chose the line graph, as it is the most appropriate way to represent the data that changes over time. The line graph conveys the message more efficiently and clearly than reporting the data in tabular form.

Solution 2: Graphical Representations of Data

Pie chart displaying the expenses of a company

The pie chart visually represents the data of the expenses incurred by a company in different categories. The chart shows the distribution of the expenses in different categories, and it helps in identifying the areas where the company is spending more or less. The editor chose the pie chart, as it is the most appropriate way to represent how much of the company’s budget is being allocated to each category. The pie chart conveys the information in a clear, concise and aesthetically pleasing way.
